Answer:
Lets calculate the value for each expression to get the answers
f(x) = x² + 6x + 9
g(x) = x² - 9
(f+g)(x) = x² + 6x + 9 + x² - 9
(f+g)(x) = 2x² + 6x
(f+g)(x) = 2x(x + 3)
(f-g)(x) = x² + 6x + 9 - (x² - 9)
(f-g)(x) = x² + 6x + 9 - x² + 9
(f-g)(x) = 6x + 18
(f-g)(x) = 6(x + 3)
(f×g)(x) = (x² + 6x + 9)(x² - 9)
(f×g)(x) = x⁴ - 9x² + 6x³ - 54x + 9x² - 81
(f×g)(x) = x⁴ + 6x³ - 54x - 81
(f÷g)(x) = (x² + 6x + 9) / (x² - 9)
(f÷g)(x) = (x+3)(x+3) / (x+3)(x-3)
(f÷g)(x) = (x+3)/(x-3)
Area of a square=side²
Data:
area=1230 mm²
Therefore:
side²=1230 mm²
side=√1230 mm²≈35.07 mm
Answer: the length of the side would be 35.07 mm
From 4 p.m to 8 p.m, there are 4 hours. Each hour is composed of 60 minutes. This means that the total number of minutes is equal to 240. Thus, we determine the ratio of her time in doing the homework by dividing 10 minutes by 240 minutes, giving us the answer of 10:240 equal to 1:24.
